Q25 of 38 Page 83

A convex lens of focal length 20 cm can produce a magnified virtual as well as real image. Is this a correct statement? If yes, where shall the object be placed in each case for obtaining these images?

Yes, the statement is correct.


To get the magnified virtual image, the object is to be placed between the optical centre of the convex lens and the focus F1 of the convex lens. The image formed will be virtual and magnified.



However, for obtaining a magnified real image, the object should be placed in between F1 and 2F1 of the convex lens.

Sudha finds out that the sharp image of the window pane of her science laboratory is formed at a distance of 15 cm from the lens. She now tries to focus the building visible to her outside the window instead of the window pane without disturbing the lens.
